Abstract

IN DE 37 02 490, A METHOD FOR DATA TRANSMISSION IS DESCRIBED IN WHICH DATA FROM PICTURE ELEMENT BLOCKS IS CONVERTED INTO DIGITAL SIGNALS WHICH ARE CODED WITH VARIABLE WORD LENGTHS. IN DOING THIS, THE DIGITAL SIGNALS ARE RECORDED IN BLOCKS WITH AN AVERAGE LENGTH. BLOCKS WHICH ARE NOT COMPLETELY FULL ARE FILLED UP WITH DATA FROM OTHER BLOCKS. IN ORDER TO IMPROVE (I.E, REDUCE) THE INTERFERENCE SUSCEPTIBILITY, DIRECT COMPONENTS AND SIGNIFICANT ALTERNATING COMPONENTS ARE RECORDED AT FIXED INTERVALS. IF FAULTS HAVE OCCURRED IN THE TRANSMISSION CHANNEL OR STORAGE MEDIUM THEN, HOWEVER, THE DATA OF A BLOCK WHICH IS DISTRIBUTED OVER OTHER BLOCKS CANNOT BE DECODED.ACCORDING TO THE INVENTION, EVERY BLOCK IS FED WITH AN ADDRESS INFORMATION FLAG (FL) AND ADDRESS POINTER INFORMATION (POI) AS WELL AS DIRECT VOLTAGE VALUE AT A PREDETERMINED POINT. USING THIS SUPPLEMENTRY INFORMATION, AN IMPROVED RESYNCHRONIZATION CAN BE CARRIED OUT IN THE CASE OF A FAULT IN THAT ALTERNATING COMPONENTS DISTRIBUTED OVER OTHER BLOCKS CAN ALSO BE RETRIEVED FROM MEMORIES (9, 10) AND DECODED.
